The image display contents specific to the second screen 60 include, for example, an image quality setting image of the second screen 60 and the like. Therefore, in the display restricted state of the first screen 50, the image control unit 100 displays a blackout image as a corresponding image even if an operation request operation by the driver is detected while an image specific to the second screen 60 is being displayed. The image (or whiteout image) is displayed to maintain the display restricted state of the first screen 50 .

The image control unit 100 shown in FIG. 2 receives a notification when the state determination unit 110 determines that the operation related to the display on the first screen 50 is completed after the display restriction state of the first screen 50 is released. In response, the image control unit 100 returns the first screen 50 to the display restricted state.

Under the configuration described above, the first image displayed on the first screen 50 of the CD 5 can be changed according to the acquisition status of sensing data by the image control section 100 . The driver may not be able to concentrate on driving if a display change such as display movement on the first screen 50 of the CD 5 comes into view while driving the vehicle 2 . Therefore, the driver can set the display of the first screen 50 to a restricted state while the operation related to the display on the first screen 50 is unnecessary.

In this display restricted state on the first screen 50 , the driver operates the vehicle equipment on the second screen 60 . However, since the display area of the second screen 60 is narrower than that of the first screen 50, the information that can be displayed on the second screen 60 at one time is limited compared to that of the first screen 50. FIG. Further, the driver performs operations related to the display of the second screen 60 via steering operation switches or the like. Therefore, it is assumed that the driver will feel dissatisfaction because the driver will operate the display of the second screen 60, which is less operable than the first screen 50 that can be operated directly on the touch panel. be.
